(588ag) High Pressure Hydrogenation of CO2 to Methanol Beyond Thermodynamic Equilibrium

Continuous hydrogenation is generally carried out continuously on a very large scale or in batch for small scale production in the fine chemicals industry. Flow hydrogenation in milli-structured pack-bed reactors offers the opportunity to dramatically reduce the footprint, better manage highly exothermic reactions and improve selectivity. This presentation will focus on continuous hydrogenation on different substrates. Emphasis will be placed on the scalability of this technology through the numbering up approach. These new processes are based on the intensification of reactions in milli-structured reactors fabricated by diffusion bonding.

The first examples will be related to different liquid substrates such as myrcene, fatty acid or acetophenone and will demonstrate the advantages of this technology to handle very exothermic reactions or to manage selective hydrogenation.

The second part of the presentation will show how this technology can be used to perform carbon dioxide hydrogenation to produce a molecule of interest for energetic transitions such as methane or methanol.
